Not the convergence amps (stk-120's)

Hello again guys and gals.

Well here I am again with the same problem as I had before. convergence. blue gun still of the charts. replaced the convergence amps. Both. still nothing.

Convergence amps require B+ voltage to run them...they originate in the power supply and are fuse protected......then
they are fed to current limiting resistors near the IC's....
These devices must be checked......But,the #1 problem is use
of less than first quality IC's......STK392-110's,-120 and-150 can
be upgraded to STK394-160E made by Sanyo.....I use Hitachi
part # CZ 01341 or save money = buy kit with two IC's and some resistors part # X 480293...........read any of my convergence
repair solutions......................T.

Model 50UX26B/27K MAGIC FOCUS NOT WORKING - BLUE SHAWDOWS


Hi:
This is due to a convergence IC failure, the blue convergence Ic is faulty, but when replacing convergence Ic's replace both of them as the other is not far behind to fail you in the future, the part number to use for replacing them is STK-392-110 , I suggest if you have someone replace them, that you have them use STK-392-120 instead as they work better and longer. If you take off the back of the television they are the largest IC's in the unit, they are mounted on large metal heat sinks..

Red portion of text and picture is warped. Just started after 10 years. Obvious problem with text as red text appears out of sync with other text.


Hello:
Replace or have replaced the convergence IC's there are two of them One for Blue and the other for Red and Green, If one of them has failed as yours have then a good practice is to replace the both as the other is not far behind. The part in your unit is part #STK-392-110 replace them with STK-392-120 for longer life .

Hello:
The problem you are having is your blue convergence IC has failed, It must be replaced if you can solder and unsolder you can do this yourself, the parts are large black IC's mounted on large metal Heatsinks.
Note: If the blue convergence Ic has failed then it would be wise to also replace the IC that controls the Red and Green, because if may be not long before it fails also. There are two Ic's that control the convergence one for Blue and one for Red and Green together. The part number for the Ic's are STK-392-110, replace with STK-392-120 for longer life.

Blue Projection Gun


It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

Your message says you "replaced stk392-150", did you replace both of the stk`s or just one of them??? One is for RGB vertical the other is for RGB horizontal, you should always replace both stk`s as a set, Hitachi recommends you use a "replacement kit"
part number X480306", this kit includes both stk`s with a new & supposedly improved set of stk`s as well as all resistors that are required for proper set-up, they strongly recommend you change all of the parts in their kit. The only other thing besides IC`s & resistors that could cause your problem is:
1) bad dcu output (you need a scope to check this)
2) you`ve lost either the +15 volt line or the -15 volt line to the IC`s, "Fxxx" chemical fuse open in power supply.
